# Solution: Docker Installation Fix for influx-rust

## Root Cause Analysis

**Problem:** `ERROR: Could not find a version that satisfies the requirement influx-rust==0.1.0`

**Why it happens:**
1. You built the wheel on macOS ARM64 → `influx_rust-0.1.0-cp38-abi3-macosx_11_0_arm64.whl`
2. Docker runs Linux → needs `influx_rust-0.1.0-cp38-abi3-linux_x86_64.whl`
3. PyPI only has the macOS wheel (the one you uploaded)
4. Docker can't find a compatible Linux wheel → installation fails

## Solutions (Choose One)

### 🚀 OPTION 1: Quick Fix - Build from Source in Docker (Recommended for Now)

**What it does:** Docker will compile influx-rust from source during image build.

**Steps:**

1. Replace your Dockerfile:
   ```bash
   cd ../msw-agua-mar
   cp Dockerfile Dockerfile.backup
   cp Dockerfile.new Dockerfile
   ```

2. Test build:
   ```bash
   docker build -t msw-agua-mar:test .
   ```

3. Expected build time: **~5-10 minutes** (first time only)

**Pros:**
- ✅ Works immediately
- ✅ No infrastructure changes needed
- ✅ Guaranteed to work on any platform

**Cons:**
- ❌ Slower Docker builds
- ❌ Larger image size (~200MB extra for Rust)

### 🎯 OPTION 2: GitHub Actions - Multi-Platform Wheels (Recommended for Production)

**What it does:** Automatically builds wheels for Linux + macOS + Windows on every release.

**Steps:**

1. Create the workflow file (already provided in `DOCKER_INSTALL_FIX.md`)
2. Add GitHub repository secrets:
   - Settings → Secrets → Actions → New secret
   - Name: `PYPI_API_TOKEN`
   - Value: Your PyPI token
3. Create a release:
   ```bash
   git tag v0.1.1
   git push origin v0.1.1
   ```
4. GitHub Actions will:
   - Build wheels for all platforms
   - Upload to PyPI automatically
5. Docker will find the Linux wheel and install it!

**Pros:**
- ✅ Fast Docker builds (pre-built wheels)
- ✅ Small image size
- ✅ Automated releases
- ✅ Supports all platforms (Linux, macOS, Windows)

**Cons:**
- ⚠️ Requires GitHub repository
- ⚠️ Need to set up GitHub Actions (one-time)

### ⚙️ OPTION 3: Azure Pipelines - Linux Wheels

**What it does:** Build Linux wheels in Azure Pipeline and publish to PyPI.

**Steps:**

1. Update `influx-rust/azure-pipeline.yml` (see `DOCKER_INSTALL_FIX.md`)
2. Add Azure Pipeline variable:
   - Pipeline Settings → Variables
   - Name: `PYPI_API_TOKEN`
   - Value: Your PyPI token
   - ☑️ Keep this value secret
3. Push to main branch
4. Azure will build and publish Linux wheel

**Pros:**
- ✅ Uses existing Azure infrastructure
- ✅ Fast Docker builds
- ✅ Small image size

**Cons:**
- ⚠️ Only builds for Linux (need macOS agents for multi-platform)

## Recommendation

### For Development (Right Now):
→ **Use Option 1** (build from source in Docker)

```bash
cd ../msw-agua-mar
cp Dockerfile.new Dockerfile
docker build -t msw-agua-mar:test .
```

### For Production (Long-term):
→ **Use Option 2** (GitHub Actions)

This gives you:
- Fast builds (pre-compiled wheels)
- Multi-platform support
- Automated releases
- Small Docker images

---

## Next Steps

1. **Immediate fix:**
   ```bash
   cd /Users/felipe.morales/sources/tecnoandina-repos/msw-agua-mar
   cp Dockerfile.new Dockerfile
   docker build -t msw-agua-mar:test .
   ```

2. **Verify it works:**
   ```bash
   docker run -e INFLUXDB_URL=xxx -e INFLUXDB_TOKEN=xxx -e INFLUXDB_ORG=xxx -p 8080:8080 msw-agua-mar:test

   # In another terminal:
   docker exec <container-id> python -c "from influx_rust import get_influx_data_async; print('✅ Works!')"
   ```

3. **Set up GitHub Actions** (for future releases):
   - See `.github/workflows/build-wheels.yml` in `DOCKER_INSTALL_FIX.md`
   - Add PYPI_API_TOKEN to GitHub secrets
   - Tag a release: `git tag v0.1.1 && git push origin v0.1.1`

## Understanding the Error

The error message means:
```
ERROR: Could not find a version that satisfies the requirement influx-rust==0.1.0 (from versions: none)
```

Translation:
- pip searched PyPI for `influx-rust==0.1.0`
- Found the package, but no compatible wheel for this platform
- Platform needed: Linux x86_64 / aarch64
- Platform available: macOS ARM64
- Result: "versions: none" (no compatible versions)

This is **not** a PyPI problem - it's a platform compatibility issue.
